KC HiLites Daylighter Off-Road Lights sets have been a leading choice in all-terrain auxiliary light systems for more than 30 years. Each Daylighter kit comes with two 6-inch Round Daylighter Off-Road lamp housings, a fully assembled wiring harness, two 130W halogen long-range bulbs, which are 285,000 candlepower beam per light, and a pre-terminated wiring harness with a 40-amp relay and an in-cab control switch. Daylighter Off-Road Lights use a heavy-duty rubber gasket, or bulb holder, that isolates all the elements of the lamp, including the lens, the reflector, and the bulb, from the vagaries of weather. The kits also include a patented shock mounting system, updated so that it requires no extra drilling. This shock mounting system isolates the lamp unit from the mounting bracket, or surface on which the light is mounted, to reduce lamp failure due to vibration. It's a shock mount that can endure the extremes of off-road racing. With its ?" posts these shock mounts install most anywhere. The kit also includes two yellow "smiley face" lamp covers.
